I know that this won't work because ST_Touches works for only two arguments. But this should show what I'd like to do. How is it possible to insert all the results of a SELECT-statement into this ST_Touches function?

Thanks for any suggestions. =)

EDIT:

Ok, I just found out that I get the same result set with this statement:

SELECT layera.name
FROM layera
WHERE ST_Touches(layera.geom,(SELECT layera.geom FROM layera WHERE layera.nr = 5134))
